Bently Nevada 350900 High Temperature Velocity Sensor

Description

The 350900 High Temperature Velocity and Acceleration Sensor (HTVAS) provides a continuous acceleration and velocity output, allowing the customer to protect their machine with an velocity signal while simultaneously capturing the acceleration signal for machinery diagnostics.Its design is primarily for use with the 3500/42M and 3500/44M monitors. When attaching the HTVAS to a

3500/42M or 3500/44M monitor you must use the acceleration and velocity signals from the transducer on a separate channel pair (such as channels 1 and 3) or on separate monitors.The 350900 High Temperature Velocity and Acceleration Sensor (HTVAS

separates the high-temperature sensing element from the signal conditioning electronics, with the two permanently connected via a hardline cable. This arrangement allows you to mount the sensing head on surfaces with temperatures as high as +482 °C (+900 °F),while installing the signal conditioning electronics in a cooler location. Eliminating connections between the sensing head and its associated signal conditioning electronics also eliminates a significant source of potential transducer failures (connector problems). This achieves overall transducer system performance comparable to other casemounted vibration transducers, but permits use at significantly higher temperatures.
